Extended Width (E-Class) Housing

The 4", 6" and 8" turbine meters are available with an extended width housing. The 4" E-Class is available in all pressure ratings while the 6" and 8" E-Class Housings are available in either 175 or 740 PSIG working pressures.

Straightening Vanes

Straightening Vanes are recommended by the A.G.A. Report No. 7 as a means to condition the gas flow to a normal pattern, enabling accurate measurement by the downstream turbine meter.

Restrictor Plate

Restrictor plates limit the flow rate through the meter and prevent overspeeding of the rotor. They are normally installed 5 pipe diameters downstream of the meter between flanges.

Lubrication

Turbine meters require routine maintenance, including lubrication, to insure measurement accuracy and enhance the service life of the meter. Two types of lubrication pump kits are available depending on the working pressure of the meter. For meters operating up to 500 PSIG, a plunger-type pump is available (Part Number 93723K002). For meters operating over 500 PSIG, use the single speed hydraulic hand pump (Part Number 93723K001).

AccuTest Field Prover

The AccuTest Field Prover includes the sensor cables, signal conditioner in a case, DAQ card, computer interface cable, and software program.

Accuracy Curves

The accuracy of the turbine meter can be determined by low, medium, and high-pressure test facilities.

Low Pressure

- 350 cubic foot Bell Prover - Large Sonic Nozzle provers - 5 point accuracy curve standard

Medium Pressure

- 120 PSIG recirculating air test loop - Master turbine meters used as reference - 6 point accuracy curve standard - (30 PSIG to 120 PSIG – air)

High Pressure

- Pressures up to 1480 PSIG - Master turbine meters or sonic nozzles used as reference - 6 point accuracy curve standard

All facilities are available for recertification of existing meters.

Flow Computer RF Interface Kit

This kit allows the use of a single RF sensor to detect movement of the rotor.

Theory of Operation

Gas measurement in the U.S. and around the world is dominated by diaphragm, rotary, turbine, and orifice meters. Each serves a different segment of the gas industry and each has its own set of advantages and disadvantages.

These four main types of meters can be broken into two distinct categories: positive displacement, and inferential. Diaphragm and rotary meters fall into the positive displacement group because they have well-defined measurement compartments that alternately fill and empty as the meter rotates. By knowing the volume displaced in each meter revolution and by applying the proper gear ratio, the meter will read directly in cubic feet or cubic meters.

Turbine and orifice meters have no measurement compartments to trap and then release the gas. These meters are categorized as inferential meters in that the volume passed through them is "inferred" by something else observed or measured. In the orifice meter the volumes are determined by knowing the inlet pressure, differential pressure, plate size, and piping characteristics, all of which "infer" the flow rates that in turn can be integrated over time to provide the volume.

Turbine meters, also called velocity meters, "infer" the volume of gas passing through them by measuring the velocity of the gas stream. Gas moving through the meter impinges on rotor blades resulting in a rotational speed that is proportional to the flow rate. The volume is determined by counting the number of meter rotations.

As defined in A.G.A. Report #7, the turbine meter consists of three basic components:

1. The body which houses all of the parts and physically contains the gas pressure.

2. The measuring mechanism consisting of the rotor, rotor shaft, bearings, and necessary supporting structure.

3. The output and readout device which may be either a mechanical drive to transmit the indicated meter revolutions outside the body for uncorrected volume registrations or for electrical pulse meters, it would be the pulse detector system and all electrical connections needed to transmit the pulses outside.

Gas entering the meter increases in velocity as it flows through the annular passage formed by the nose cone or upstream stator and the interior of the body. The movement of the gas over the angled rotor blades exerts a force to the rotor causing it to rotate. The ideal rotational speed of the rotor is directly proportional to the flow rate of the gas. The actual rotational speed is a function of the annular passageway size and shape, and rotor design. It is also dependent on the load that is imposed due to internal mechanical friction, fluid drag, external loading, and gas density.

A.G.A. Report #7 was written to provide recommendations as to the correct method for installing turbine meters, using their associated corrective factors, and meeting the operating requirements that pertain to axial flow type meters. Since the turbine meter is a velocity-measuring device, consideration should be given to both the upstream and downstream piping to insure a uniform velocity distribution of the gas through the meter and the rotor by reducing jetting or swirl. Construction of the turbine meter is such so as to minimize minor flow distortions that could affect meter performance. See Figure 1.

The AccuTest turbine meter utilizes a second cartridge downstream of the first or main rotor. This rotor has vanes with a different blade angle and rotates in the opposite direction of the main rotor. Since both rotors are measuring the same flow rate of gas at the same temperature and pressure, then the output registration should be the same off of both rotors. In effect, the meter is a built-in transfer prover to continuously monitor its condition.

A laptop computer, with inputs from both rotor sensors, multiplies the ratio of pulse frequencies by the ration of the calibration (K) factors to compute meter accuracy.

Accuracy = (Frequency of main rotor)/(Frequency of reference rotor) times (K Factor of reference rotor)/(K Factor of main rotor)
